CINAHL Headings: You can search for a theorist's name or their theory name in a CINAHL Headings search. Some of them have headings. You can also try searching by the Theorist's name as a keyword search (remember to put their name in quotes) or by searching for the name of their theory. You may find an article talking about the importance or history of the theory; many of the articles are about applying the theory to practice or debating the theory; books are more likely to give you an overview of the theory, the theorist, and how the theorist developed the theory.
